What is Gemini CLI?
Gemini CLI is a terminal-based AI development tool that queries and edits large codebases, generates applications from images or PDFs, and automates complex workflows using Gemini 3. Its differentiator is that it keeps build, debug and deploy work inside the command line, rather than requiring a separate editor or browser-based AI interface.
Key Features
- Terminal-native workflow: Gemini CLI runs from the command line, so build, debug and deploy tasks are handled in the environment where developers already work instead of through a separate graphical tool.
- Large codebase querying: The tool can query large codebases, letting developers ask questions about an existing repository rather than reading through files manually.
- Large codebase editing: Alongside querying, Gemini CLI can edit large codebases directly, which supports change work on projects that are too large to handle file by file.
- App generation from images or PDFs: Gemini CLI generates applications from images and PDF inputs, allowing a visual mockup or a document to serve as the starting point for a build.
- Complex workflow automation: The tool automates complex, multi-step workflows from the terminal, reducing the manual sequencing of repetitive development tasks.
- Gemini 3 model support: Gemini CLI is positioned around Gemini 3 for its build, debug and deploy capabilities.
- Migration path to Antigravity CLI: Google states that Gemini CLI was replaced by Antigravity CLI for unpaid tier and Google One users on June 18th, 2026, with further details published in a blog post. The company also notes that Gemini CLI has not been optimized for Gemini 4 Argon, and directs users who need that model to Antigravity.
Use Cases
- Large repository navigation: Developers working in big codebases can query the project from the terminal to understand structure and behavior without manually tracing files.
- Codebase-wide edits: Teams making broad changes across a large codebase can use Gemini CLI to apply edits rather than modifying files individually.
- Prototyping from visual or document inputs: A developer with a design image or a specification PDF can generate an application from that input to accelerate an initial build.
- Workflow automation: Engineers who repeat multi-step procedures during build, debug or deploy cycles can automate those sequences from the command line.
- Terminal-centric development: Developers who prefer to stay in a shell can handle build, debug and deploy tasks without switching to a separate AI interface.
Who It Is For
Gemini CLI targets developers and engineering teams who work primarily from the terminal and need AI assistance on large codebases. It addresses the problem of context switching between a shell and a separate AI tool, and the difficulty of querying or editing repositories that are too large for manual review. Teams that generate applications from images or PDFs, or that automate recurring multi-step development workflows, are the clearest fit.
Pricing
The source material does not publish price points for Gemini CLI. It does reference an unpaid tier alongside Google One users, and states that both groups were moved to Antigravity CLI on June 18th, 2026.
Frequently Asked Questions
What is Gemini CLI used for?
Gemini CLI is used to query and edit large codebases, generate applications from images or PDFs, and automate complex workflows from the terminal. It covers build, debug and deploy tasks using Gemini 3.
Is Gemini CLI still available?
Gemini CLI was replaced by Antigravity CLI for unpaid tier and Google One users on June 18th, 2026, according to Google. Users in those groups are directed to Antigravity CLI and the accompanying blog post for details.
Which Gemini model does Gemini CLI use?
Gemini CLI is built around Gemini 3 for its build, debug and deploy capabilities. Google states that Gemini CLI has not been optimized for Gemini 4 Argon, and that users who need Gemini 4 Argon should use Antigravity instead.
Who should use Gemini CLI?
Gemini CLI suits developers who work from the command line and need to query or edit large codebases without leaving the terminal. It is also relevant for those generating apps from images or PDFs and automating multi-step development workflows.
What are alternatives to Gemini CLI?
Antigravity and Antigravity CLI are the alternatives named in Google's own guidance, since Antigravity CLI replaced Gemini CLI for unpaid tier and Google One users. Antigravity is also the recommended path for Gemini 4 Argon.
